11 Claims.

This invention relates to display stands particularly adapted to beemployed in the displaying of various perishable commodities such, forexample, as lettuce, celery and similar produce.

An important object of the present invention is to provide a generallyimproved display stand on which various perishable commodities,especially those which are most susceptible to deterioration by reasonof improper or unsuited atmospheric conditions, may be subjected to suchtreatment, while on display, as will maintain them fresh and preservetheir natural characteristics. To the above and other ends the inventioncontemplates, in a display stand, means for so directing currents of airthrough a plurality of finely divided sprays of water as to cause asuitable amount of moisture to be picked up by and carried along withthe air currents, means for uniformly delivering such moisture to thedisplayed vegetables in the form of a mist, and means for insuringcontinuous movement of air currents not only directly above thevegetables but also directly beneath as well as generally between thesame.

Other objects and advantages of the invention will become apparent fromthe following description when taken in connection with the accompanyingdrawings,in which- Fig. 1 is a perspective view of a display standembodying the present invention; Fig.. 2 is a plan view of the displaystand; Fig. 3 is a longitudinal, sectional view taken on line 3-3 ofFig. 4; Fig. 4 is a transverse sectional view taken on line 4-4 of Fig.3; Fig. 5 is a transverse, sectional view of a modified form of mainbaflie; Fig. 6 is a plan view of another modified form of main bafile;Fig. '7 is a fragmental, sectional view showing a pair of adjustabledistributing bailies that may be employed in lieuof the fixeddistributing baiiles of Fig. 3; Fig. 8 is an enlarged view, partly insection and partly in elevation, showing the details of construction ofthe respective spray nozzle units, all of which appear in Fig. 3 and oneof which is illustrated in Fig. 4; Fig. 9 is an enlarged view showing inend elevation the motor of Fig. 3 and illustrating the manner in whichit is yield'ably supported with relation to its associated airconduit,.and Fig. 10 is a view in side elevation of the motor and itsmounting as they appear from the left in Fig. 9.

Although the invention may be incorporated in display stands of variousdesigns, it is herein illustrated as embodied in an apparatus compris-5-5 ing a cabinet C, which includes rear, front and I end wall sectionsIII, II, and I2, respectively, and

is adapted to accommodate in the lower part thereof a plurality ofsuitable receptacles, not shown, for the display of such commodities asare commonly known as dry vegetables, for ex- 5 ample potatoes, turnips,squash and other similar produce.

Associated with the cabinet C, is an air humldifying unit M, which isadapted to deliver moisture to the vegetables to be treated and to 10insure continuous movement of airnot only directly above the vegetables,but also directly beneath as well as generally between the same. Thehumidifying unit I4 is so incorporated into the apparatus as a wholethat it assumes an in- 15 clined or'forwardly tilted position, as willbe readily understood from an inspection of Fig. 4.

As shown most clearly in Fig. 3, the humidifying unit It includes ahorizontally disposed conduit l6, at the inlet end of which is mountedan 20 electric fan unit I I, the motor I8 of which is yieldablysupported by a resilient mounting 20.

Referring particularly to Figs. 9 and 10, it will be noted that themotor mounting 20 includes a pair of arcuate straps 2|, which areclamped to 2 the motor housing and to which are connected the inner endsof a plurality of tension springs 22. These springs are disposedradially with respect .to the axis of the conduit i6 and are connectedat their outer ends to a plurality of ten- 30 sioning hooks 24, thescrew-threaded and nutcarrying ends of which extend through a plu-'rality of longitudinally disposed arms 25, secured to an annular band26, which embraces and is suitably connected to the outer end of the 35conduit Hi. It has been found that the relatively simple motor mountingjust described not only serves as a convenient means for supporting themotor in a proper position with relation to the conduit l6, but alsoserves to satisfactorily obviate the transmittal of motor vibrations tothe humidifying unit and its several associated parts.

Referring particularly to Figs. 1 to 4, it will be noted that theconduit I6 terminates in a distributing chamber 21, the inclined sidewalls 28 of which are disposed in a parallel relation and the inclinedbottom wall 30 of which is provided with a drain pipe 31. water which issupplied y th s v a s ay n0zzles, hereinafter described, gravitates intothe v distributing chamber 21, the drain pipe 3| is by preferenceconnected to the lowermost or substantially the lowermost point of thatchamber,

Inasmuch as any surplus 50 as shown in Fig. 4, so as to insure completedrainage thereof at all times.

As shown most clearly in Fig. 3, the distributing chamber 21 includes,in addition to its side walls 28 and its bottom wall 30, a pair of endwalls 32 and 34, the former of which is straight and extends verticallyfrom the wall of the conduit l6, and the latter of which is curved andextends upwardly from the bottom wall 30. The side walls 28 and the endwalls 32 and 34 of the distributing chamber 21 terminate insubstantially the same plane and are connected respectively at theirupper ends to the upwardly and outwardly inclined side walls 35 and endwalls 36 of a hopper-like header H. The side walls 35 of the header Hterminate in vertically disposed front and rear wall sections 38 and 40which are so curved or shaped at their upper ends as to afford front andrear down draft deflectors 4| and 42, whereas the end walls 36 of theheader terminate in transversely extending ledges 44, with which areassociated upwardly extending end wall sections 45. In order that thehumidifying unit |4 thus far described may be conveniently supported bythe cabinet C, there are provided a plurality of hanger lips 46, 41, and48 which are carried by the header wall sections 38, 40, and 45,respectively, and are adapted to overhang the upper ends of the wallsections I0, II, and I2 of the cabinet 0, within which the humidifyingunit is adapted to snugly fit. For the sake of appearance in thefinished apparatus and in order to guard or protect the down draftdeflectors 4| and 42 against accidental or unintentional blows orimpacts which might tend to bend or otherwise unduly deform the same,they are housed within or partially enclosed by a pair of longitudinallydisposed hoods 50 and carried, respectively, at the front and the rearmargins of the humidifying unit I4.

In order that the vegetables, to which moisture is to be supplied and inthe immediate vicinity, of which air currents are to be induced oro,therwise set up. may be supported in display position, the humidifyingunit I4 is so constructed as to afford an upwardly and rearwardly inclined tray T. This tray includes the end wall sections 45 of the headerH, and a pair of longitudinally disposed side walls 52 and 54 which aresuitably connected at their opposite ends to the end wall sections 45and are spaced a substantial distance from the front and rear wallsections 38 and 40 of the header. The side walls 52 and 54 of the tray Tare formed at their lower margins with inwardly extending ledges 55,which terminate in inwardly and downwardly extending deflector lips 56.In order to lend rigidity to .the deflector lips 56, and incidentallyreinforce their associated side walls 52 and 54, there are provided aplurality of tie members 51 which extend transversely of the tray T andare secured to the deflector lips in such positions that their upper orbearing surfaces are flush with the ledges 55, which, themselves, areflush with the ledges 44. It will be appreciated that inasmuch as thetie members 51, the ledges 55 and the ledges 44 are so disposed withrelation to each other that their upper faces lie in the same orsubstantially the same plane, they are admirably adapted to support abottom 58 for the tray T. The bottom 53, in order to afford unobstructedpassage of air to the vegetables supported thereon and to permit freedisposal of any excess-moisture supplied to the vegetables while beingsubjected to treatment by the apparatus embodying the invention, is of ahighly pervious character and comprises a plurality of removable screensections 60, which are disposed adjacent each other and are collectivelysupported by the tie members 51 and ledges 44 and 55. If desired, aplurality of removable separators, one of which is indicated in Fig. 1and there indicated by the numeral 6|, may. be employed for maintainingadjacent groups of vegetables more or less separated from each other.

Disposed beneath the tray T and arranged centrally or substantiallycentrally of the header H and the rectangular opening leading into theheader from the distributing chamber 21, is a main baiile 62 which ishopper-like in its character and presents in plan a rectangular outline.This baffle includes a pair of upwardly and outwardly extending sidewalls 64, connected to each other at their lower margins and therepresenting a relatively sharp V-like juncture, which is common to thecentral longitudinal plane of the distributing chamber 21 and which inlength is somewhat less than the rectangular opening leading from thatchamber into the header H. As shown most clearly in Fig. 2, the endmarginal edges of the side walls 64 are inclined upwardly and outwardlytowardthe sides of the header H as well as toward the ends thereof sothat corresponding adjacent edges, to which are connected end walls 65,present, when projected, a V-shaped outline, the projected apex of whichfalls well within the projected outline of the passage leading from thedistributing chamber 21 into the header. Taking into account thegeometrical characteristics of the main baffle 62 (as determined by therelation of its side walls and end walls 64 and 65 to each other) andthe relation of that bailie to the opening leading from the distributingchamber 21 to the header H, it will become apparent that the side wallsnecessarily overlie corresponding or like portions of that opening andthat the same is also true with regard to the end walls.

As shown in Figs. 3 and 4, the main baflle 62 is so spaced from theinclined side walls 35 and end walls 36 of the header H as to formtherewith a pair of end air ducts 66 and a similar number of side airducts 61. In order to effect proper distribution of air passing throughthe ducts 66 and 61, there are provided a plurality of diversion baflies63 and 10, which are disposed, respectively, beneath the side walls andend walls 64 and 65 of the main baflie and are utilized asmain-baiile-supporting means. These diversion baffles 68 and 16 arepreferably connected to, and are therefore removable with, the mainbaffle 62, but, if desired, they may be connected to the respectivewalls 35 and Y36 of the header H. It will become apparent from aninspection of Figs. 2 and 4 that regardless of whether the diversionbafiies 68 and are connected to the main baffle 62 or to the headerwalls 35 and 36, they will properly center the main baille with respectto the opening leading from the distributing chamber 21 into the headerH and will maintain that bafile against undue displacement, but it is tobe understood, of course, that any suitable fastening means ofconventional type, not shown, may be employed, if desired, for anchoringthe bathe in the position which it normally assumes when introduced intothe header. Inasmuch as the main baflie 62 is located directly beneaththe tray T and may, therefore, receive a certain amount of any excessmoisture delivered to the vegetables undergoing treatment, it

becomes desirable to provide the baflle with a plurality of perforationsor drain openings "II, which are so located as to permit watercollecting in the bafile to drain therefrom into the distributingchamber 21 from which it is relieved by the drain pipe 3! as previouslydescribed.

It is desirable that air passing through the conduit I6 under the actionof the fan I! be directed into the air ducts 66 and 61 in properlyproportioned amounts, and to that end the curved end wall 34 of thedistributing chamber 2'! is utilized as a distributing baifie inassociation with a pair of downwardly projecting similarly curveddistributing baflles l2 and 14 which are carried by the main baiiie 62.The distributing baflles 12 and I4 occupy such positions with relationtoeach other and to the end wall 34 of the distributing chamber that theair which is deflected upwardly into the air conduits 66 and 61 by themand by the end wall is proportioned in accordance with the capacity ofthe respective air ducts. Taking into account the, fact that the airentering the air ducts 68 and 61 is proportioned according to therespective air' duct capacities and the fact that the diversion baflles68 and 18 are so disposed as to'cause the air streams peculiar to theair ducts to assume fanlike characteristics, it follows that there willbe effected a uniform delivery of air to the tray T in the vicinity ofits ends and sides.

In order that the air'prior to its delivery to i the vegetables may besupplied with moisture in a highly divided state, there are provided aplurality of'spray nozzle units 15, one of which is located at the inletend of each of the air ducts 66 and one of which is disposed directlybeneath the main deflector 82 and in the vicinity of the junction of theair ducts 81. These spray nozzle units 15 are individually connected tosuitably supported branch pipes 16, equipped with handoperated controlvalves TI and connected to a manifold I8, which is adapted tocommunicate with a source of water supply, not shown. Each of the nozzleunits I5'is inclined with respect to one or another vertical plane, aswill be readily understood from an inspection of Figs. 3 and 4, andincludes a base plate 80, to which is connected a spray head 8|, adaptedfor screw-thread connection with any one of the branch pipes 18.Suitably connected to the base plate 88, is a pair of supporting rods82, to the upper ends of which is connected an impact or diffusing plate84 which is so shaped as to present a curvilinear surface, againstwhich-is forcibly directed a fine stream of water issuing from thenozzle orifice or aperture 85. The diffusing plate 84 is provided withacap-like closure 88, and, preferably, contains a suitable sound-dampingmaterial,

'such' as lead which has been found to operate stream of water againstthe diffusing plate. Itis to be here observed that in order to obtainthe most satisfactory difiusing action, the impact area (namely thatarea of the diffusing plate 84 against which the stream of waterimpinges) 'must be kept free of excess moisture, which would tend tocollect on and cling to the diffusing plate surface. In thepresentinstance the efliciency of each of the diffusing plates 84 is especiallypronounced, inasmuch as any water tending to accumulate on the surfacethereof is drained, due to the angular disposition of the respectiveunits, onto one of the supporting rods 82, downwhich it gravitates andfrom which it drips into the distributing chamber 2'1, to be thereaftercarried away by the drain pipe 8|.

Although the form of main baflle 82, shown in Figs. 1 to 4, has beenfound to effect a. substantial flow of air in the immediate vicinitydirectly above the same and in ally upwardly through the tray '1, suchflow may be somewhat altered to obtain a more nearly vertical movementof air upwardly through the tray in the vicinity immediately above thebaffie by resorting to the form of main baffle 62' indicated in Fig. 6.This baflie is identical in all respects to the baflle 62, except thatit is provided throughout or substantially throughout the extent of itsside and end walls 84' and 85', respectively, with a plurality ofperforations 81, which, as will be readily understood, permit a portionof the air which is directed into the air ducts 86 and 81 to passand tobe forcibly directed upwardly through the baflie and thence into andthrough the tray.

If for any reason a down draft through the tray T in the vicinityimmediately above the main baflie is desired,'the form of main'bafliei1- lustrated in Fig. 5 and there indicated by the numeral 62 may besubstituted for either of the main baflles above described. a The baflle62" is identical with the baiile 62 except for the fact that its sideand end walls 64" and 65", respectively, are provided with a pluralityof louvers 88, the lips of which are adapted to occupypositions withinthe air ducts 66 and 61. It is obvious that as the air moves upwardlypast the louver lips 88, there is effected an ejector action, as regardsthe interior of the baffle, which .will cause a pronounced down draftthrough the tray in the vicinity immediately above the baille.

Although the distributing baiiles I2 and I4 shown in Fig. 3 have provedsatisfactory, it may be well to mention that adjustable baflles of thetype shown in Fig. 7 and there indicated by .the numerals 12' and 14'may be employed, if desired. These baflles are frictionally held withinsuitable guides 90, carried by side walls 28' of the distributingchamber 21, and may be moved to various positions of adjustment in orderto varythe proportions of air to be delivered to the several air ductswhich are located beneath the main bailie 62" and corresponding, ofcourse, to the air ducts 86 and 8'! hereinbefore described. As to themain baille 82", it may be identical with any one of the main baflles,namely, 62, 62', and 62", hereinbefore described, except for a pair ofguard wings 9| with which it is provided and which serve to maintain, ineffect, continuity as between itself and the distributing baiiles I2 and14' regardless of the positions of adjustment to which they may bemoved.

Aside from the modifications herein shown and described, it will beunderstood that various other changes may be made without departing fromthe spirit of the invention or the scope of the following claims.
